Reply to comment by DeusRexy in ELI5 why do electric vehicles have one big battery that's hard to replace once it's expired, rather than lots of smaller ones that could be swapped out based on need (to trade off range/power/weight)? by ginonofalg
>Each battery is different, but each of the small batteries I would say the average is something like a Capri Sun pouch, some are bigger, some are smaller. Also, they are pouches, with layered cathode and anode layers (negative/positive), with separator layers between and an electrolyte slurry inside.
Not in Tesla's, they just stack a bunch of A cell, B cell or D cell sized LiIon batteries in the box.
